submariner

The submariners of World War One were true pioneers of submarine warfare, especially on this scale.

Yes, there was muddle and delay, and many in Russia, not least families of those lost, will be asking questions about how the news came out, and whether international help at an earlier stage could have saved any of the submariners.

The lock-out system is a reversible air-lock that enables submariners to leave the vessel, harvest pearls from the sea-bed, then return to the submarine.
